Smartphone control of various devices is becoming somewhat ubiquitous, and controlling your Arduino-powered project with an Android device is easy thanks to the use of a Bluetooth shield and a free or customised app.

Once excellent example of this has been demonstrated by the ICT Tools for Teachers program, who have a hybrid LEGO/Arduino-controlled robotic vehicle used in technology teaching areas. As you can see in the video below, the robot has a decent speed and can deal with the rigours of experimentation:

If you're looking into starting with Arduino and robotics, such as controlling a stepper motor (or DC motors) from your Arduino or compatible, check out our HBRIDGE: DC/stepper motor shield.

Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners' guide and documentation - motor control couldn't be any easier. For more information and to order, visit the HBRIDGE: page.
